Group 49 Lithium Iron Phosphate Deep Cycle Battery, 24V 100Ah, ABYC Certified

WEST MARINE Group 49 Lithium Iron Phosphate Deep Cycle Battery, 24V 100Ah, ABYC Certified

Maximum power meets extended runtime. The WEST MARINE Group 49 Lithium Iron Phosphate Deep Cycle Battery in 24V 100Ah is engineered for serious boaters who refuse to compromise on either power delivery or time on the water. This is the deep-cycle battery for anglers running multiple trolling motors, captains managing complex marine electronics, and water sports enthusiasts powering high-power audio systems that demand sustained, reliable energy throughout extended outings.

Built on chemically stable, resilient LiFePO4 chemistry, the advanced battery management system protects against overcharging and over-discharging while maintaining an IP65 protection rating for demanding saltwater and freshwater marine environments. With exceptionally high energy density and power output, this Group 49 lithium battery delivers up to 10 times the lifespan of traditional lead-acid alternatives, translating to years of dependable service and substantial cost savings that add up fast. The lightweight design won't burden your vessel's weight distribution or compromise fuel efficiency the way heavier lead-acid batteries do, keeping your boat responsive and economical.

Deep-discharge capability means you can safely access the full 100Ah capacity without risking cell damage or premature degradation, giving you genuine reserve power when conditions demand it. Stable voltage output keeps your trolling motors spinning at full strength, your navigation systems running reliably, and your accessories operating at peak performance throughout every charge cycle.

Fast-charging efficiency gets you back on the water quickly with minimal downtime between trips, while zero maintenance requirements and eco-friendly LiFePO4 chemistry eliminate the sulfation and corrosion that plague conventional marine batteries. This is 24-volt deep cycle power redefined: maximum amp-hour capacity, lightweight efficiency, and the reliability to deliver day after day.

This battery is ABYC certified, giving boat owners and marine professionals confidence that it meets established safety standards for use in recreational boats and marine electrical systems.

What is ABYC?

The American Boat & Yacht Council (ABYC) is a non-profit, member organization that develops voluntary global safety standards for the design, construction, maintenance, and repair of recreational boats. ABYC also provides standards-based technical education and training to help marine professionals build skills, stay current, and advance safety across the boating industry.
